Abstract

PROBLEM TO BE SOLVED: To facilitate tying reinforcing bars, enable non-experts to reliably and efficiently tie the bars and also reliably and efficiently tie even linear objects other than the reinforcing bars and mouths of bags. SOLUTION: A binding tool includes, at an end of a band body 1 made of synthetic resin exhibiting an approximate V-shape and having a hinge 2 at the center, a buckle 5 opened toward the other end and having a shutting claw 7 inside, and at the other end a locking part 9 having locking teeth 11 to be locked to the claw 7 of the buckle 5 on an insertion piece 10 which can be inserted through the buckle 5. Pressure is applied in a direction that both ends of the band body 1 come close to each other with a hinge 2 as a fulcrum, thereby inserting the locking part 9 through the buckle 5 and locking the locking teeth 11 to the shutting claw 7 of the buckle 5.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a binding tool capable of easily binding objects to be bound.

The present invention is mainly used as a binding tool for binding reinforcing bars arranged in a reinforced concrete building, but is also used for binding other linear objects, binding of openings of bags, and the like. It is what is done.

[0003]

2. Description of the Related Art Hitherto, there has been adopted a means for binding the intersection of reinforcing bars arranged in a reinforced concrete structure with a wire in order to prevent the displacement. All the work of binding the reinforcing bars with the wire is performed by a professional worker.

[0004]

The above-mentioned conventional work of binding the reinforcing bars by the wire is a very troublesome work and requires a specialized worker.

SUMMARY OF THE INVENTION An object of the present invention is to provide a binding tool capable of easily binding the reinforcing bars and reliably and efficiently binding the reinforcing bars even by a specialized operator. Another object of the present invention is to bind linear objects other than rebar,
An object of the present invention is to provide a binding tool capable of reliably and efficiently binding even when binding the opening of the bag.

[0006]

In order to achieve the above object, the present invention is directed to one end and the other end of a synthetic resin band body having a substantially V shape and having a hinge portion in the center. And a buckle portion having a non-return pawl inside, and at the other end, an engaging piece that can be inserted into the buckle portion and has a locking tooth that engages with the non-return pawl of the buckle portion. The locking portion is inserted into the buckle portion and the locking teeth are locked to the check claws of the buckle portion by pressing both end portions of the band body toward each other with the hinge portion as a fulcrum. I decided to do it.

According to the present invention, by pressing both ends of the band main body with the hinge as a fulcrum in a direction in which they approach each other, the locking portion is inserted into the buckle portion and the locking teeth are non-returned to the buckle portion. As it is locked to the claws, when binding the objects to be bound, put the objects to be bound inside the substantially V-shaped band body, and in this state, the both ends of the band body approach each other. It is possible to bind the objects to be bound by a simple operation such as pressurizing.

[0008]

Embodiments of the present invention will be described below in detail with reference to the drawings. In the drawings, reference numeral 1 denotes a synthetic resin band body having a substantially V shape and having a hinge portion 2 in the center. Reference numerals 3 and 4 denote band portions opened in a V shape from the hinge portion 2, and the hinge portion 2 and the band portions 3 and 4 constitute the band body 1. Band part 3, 4
Are slightly curved in opposite directions.

Reference numeral 5 denotes a buckle portion provided at one end portion of the band body 1, that is, an end portion of the band portion 3. This buckle part 5
Has an opening 6 that opens toward the other end of the band body 1, that is, toward the end of the band 4. Inside the opening 6, a check claw that tilts in the depth direction of the opening 6 is provided. Have 7. Reference numeral 8 is also a check tooth provided inside the opening 6 so as to face the check claw 7.

Reference numeral 9 is a locking portion provided at the other end of the band body 1, that is, at the end of the band portion 4. The locking portion 9 is provided on the insertion piece 10 that can be inserted into the opening 6 of the buckle portion 5, and when the insertion piece 10 is inserted into the opening 6 of the buckle portion 5, the check claw 7 and the check tooth 8 are provided. It is configured such that locking teeth 11 and 12 which are locked between the check claw 7 and the check tooth 8 are provided between them. The insertion piece 10 has a shape extending toward the opening 6 of the buckle portion 5, and both ends of the band body 1, that is, the end portions of the band portion 3 and the band portion 4 are mutually connected with the hinge portion 2 as a fulcrum. When the insertion piece 10 is pressed in the approaching direction, the insertion piece 10 is inserted into the opening 6 of the buckle portion 5, and the insertion piece 10 is inserted so that the insertion piece 10 can be inserted smoothly.
Has a shape that is slightly curved inward.

Further, the locking teeth 11, 12 provided on the insertion piece 10
Is inclined rearward from the insertion-side tip, and when the insertion piece 10 is inserted into the opening 6 of the buckle portion 5, the buckle portion 5
Check claw 7, check tooth 8 and locking teeth 11, 12 of the insert piece 10.
The insertion piece 10 is allowed to be inserted without being locked with the opening 6
When a pulling force is applied to the insertion piece 10 inserted into the pulling direction, the check claw 7 and the check tooth 8 of the buckle portion 5 and the locking teeth 11 and 12 of the insertion piece 10 are locked, The insertion piece 10 cannot be pulled out from the opening 6.

Reference numerals 13 and 14 denote projecting portions formed in the middle of the inner sides of the band portions 3 and 4 which face each other. The band portions 3 and 4 hold down the objects to be bound, and the band portions 3 and 4 are provided.
It is intended to prevent the object to be bound from moving between them.

When binding the objects to be bound by using the above-mentioned binding tool according to the present invention, first, the objects to be bound 15 are provided between the band portion 3 and the band portion 4 of the band body 1 opened in a substantially V shape. Position. In this state, when both ends of the band body 1, that is, the ends of the band part 3 and the band part 4 are pressed toward each other with the hinge part 2 as a fulcrum, the buckle part 5 provided at the end part of the band part 3 is pressed. The locking portion 9 provided at the end portion of the band portion 4 is inserted into the opening portion 6. The object to be bound 15 is attached to the band portion 3
When the band portion 4 and the band portion 4 are fastened, the pressure applied to the band portion 3 and the band portion 4 is released.

As a result, a force is exerted on the end portions of the band portion 3 and the band portion 4 in a mutually separating direction, but at this time, the inside of the opening portion 6 of the buckle portion 5 provided at the end portion of the band portion 3 is provided. The non-return claw 7 and the non-return tooth 8 which are provided in the above-mentioned are engaged with the interlocking teeth 11 and 12 of the interlocking part 9 provided at the end of the band part 4, and the interlocking part 9 is pulled out from the buckle part 5. Is prevented. As a result, the end portions of the band portion 3 and the end portions of the band portion 4 are fixed to each other, so that the objects to be bound 15 are bound by the band body 1 with certainty.

The object to be bound 15 bound to the band body 1 as described above is pressed by the projecting portions 13 and 14 formed inside the band portions 3 and 4, and the band body 1 is held. Movement within it will be blocked,
As a result, a reliable binding state can be obtained.

[0016]

As described above, according to the binding tool of the present invention, it is possible to bind the objects to be bound reliably and efficiently by a simple operation.
